Oh. I should add that my target material is ABS which is much easer to cut than aluminum. So I don't think my exact design would work for you. But...
Yes. I am using 1m lengths of 8mm acme screws. I've settled on 500mm/min as a reasonable top speed, though it is possible that I could tweak...
Changing the software setting is easy and you can do it at the end. The tricky thing if you change the lead screw is that you can no longer use...
@GrayUK I cut my first 'real' part out and it was nearly perfect even without adjusting for runout. I compared it with an identical part which I...
I have been playing around with a similar setup to this to cut 3.175 mm thick material. My build is a bit different, but the same basic idea and...
I think I have finally got this figured out. I took a step back and decided to follow @GrayUK's advice and just carve slots in my stock instead of...
I ran some tests with different sizes to try to determine how much of this might be steps/mm. What I found was that the carriages on the x and y...
Tweaking the g-code didn't seem to make much of a difference. I've been working on other issues parallel to this one. I had to level my...
No. I can't see how it is a steps/mm issue either. If it were, then I would see proportionally larger errors as I cut proportionally larger items....
@GrayUK I have done a number of tests today and I am still scratching my head. Every time I do an 'outside' square, the part is about 0.9mm too...
@eddiejr If you want to get back into the game and want some inspiration, I put together a gallery of most of the designs posted on the DIY book...
Jonathon Duerig published a new build: This is a book scanner built out of aluminum extrusion. It is designed to get high quality scans without...
This is a complete book scanner which uses cheap point and shoot cameras to gently capture the pages of a book. The control and interface runs on...
@GrayUK I'm using a 3.175 mm (1/8") bit. I specified cutting outside the line. I'll try tweaking the size of the bit in software to test whether...
On a test cut for my new CNC router, I measured the resulting part to be 0.9mm larger than I had programmed. It was supposed to be 50mm across,...
I managed to make my first cut today. The hybrid pressure foot and dust shoe seems to work pretty well. The vacuum doesn't collect all of the...
The mechanical and wiring parts are now complete. Now just to test things out. Also it is time to start thinking about dust collection and...
This seems like the perfect application for simple rotation. Have a semi-circle tray or arm that rotates out to accept a drink. Then have it...
Yes. The rails are built into the beams. I tend to think of them as rails or beams depending on how I'm using them at the time. So I think the way...
More progress today. A first look at the X-axis and the electronics base board. No custom plates for the X-Axis gantries. Instead, I use a...
